Mechanical Rotor Seal Rubber Lobe Pump With Flange Pipe Connectors
Working Principle
Lobe pump is self-priming, valveless positive displacement pump.
Through the two parallel shafts in the synchronous gear to driven
the rotor synchronous operation, chamber form a vacuum between the
rotor vanes and casting surrounding, so that the medium was
inhaled, then displaced through the discharge-side. Pump operating
direction can be reversed by changing the direction of rotor
rotation, to be a two-way pump for reversing operation.

Structure features
The pump cavity design is so simple. All models of pumps retain
simple design styles. The fast -opening pump cover is opened to
provide guarantee for user maintenance personnel without
disassembling the pipeline. The driver can guarantee online repair.
Greatly reduced the stop time. Before and after, the upper and
lower wear -resistant internal lining design, comprehensively
ensure the non -wear of the pump shell and ensure long -term
durability. Such a simple maintenance characteristics reduce the
operating cost of the entire life cycle of the equipment.
